To @222 whom, it may concern:

Be it known that 1, ROBERT A. Beer MANN, a citizen of the United States,and a resident of Newport, in the county of Newport and State of lthodeIsland, have invented new and Improved Clips for Closing Non-MetallicCollapsible Tubes, of which the following is a full, clear, and exactdescri tion.

.L y invention has for its object to provide a clip for use in closinnon-metallic collapsible tubes, which has ns serving to hold the tube inposition when rolled- Additional objects of the invention will appear inthe following specification in which the preferred form of my inventionis described.

In the drawings, similar reference characters refer to similar parts inall the views,

Many attempts have been made to mandfacture collapsible tubes of othermaterial than metal such as paper and celluloid, because of theexcessive. cost of the manufacture of such tubes of metal, but adifliculty has been encountered in the manufacture of collapsible tubesof paper and celluloid and other materials, for the reason that it hasbeen found t be impossible to roll the nonmetallic-tubes tightly, sothat they will not spring open. When using collapsible tubes,

it is customary to roll up the end of the tube after the materialcontained in the tube has been squeezed beyondthe said tube end, and inthe use of non-metallic tubes, this cannot be done satisfactorily, asthe non-metallic tubes will spring open after they have been rolled, asstated above.
